GaAs Focusing Lenses for CO2 Lasers

Semi-insulating Gallium Arsenide (GaAs) lenses are known for their superior robustness and durability, making them an excellent alternative to Zinc Selenide (ZnSe) lenses in medium and high-power continuous wave CO2 lasers. GaAs lenses are particularly beneficial in environments where toughness and durability are crucial, as their hardness and strength make them resistant to damage from dust and abrasive particles. Unlike softer materials, GaAs lenses prevent particles from embedding in the optical surface, even with the best coatings.
